The present invention refers to pant-type absorbent articles such as pant-type diapers, sanitary pants, and incontinence pants. The pants-type absorbent article includes a front part (2), a rear part (3), and a crotch part (4), and a lateral side part (17) of the front part (2) and the rear part (3). 18, 19, 20) so that their inner surfaces face each other so as to define a waist opening (14) and a pair of leg openings (15, 16) of the pant-type absorbent article. Joined together along the side seams (12, 13). At least a part of the front portion (2) and the rear portion (3) including the lateral side portions (17, 18, 19, 20) includes an elastic laminate (21), and the elastic laminate is 1 fiber layer (22) and 2nd fiber layer (23) and the elastic film layer (24) located between them are provided. The first fiber layer (22) of the elastic laminate (21) forming an inner side facing the wearer of the elastic laminate has a basis weight of 13 g / m2 to 30 g / m2, and the first The basis weight of the fiber layer (22) is 10 to 300% higher than the basis weight of the second fiber layer (23) of the elastic laminate, and the first fiber layer (22) is Facing each other along the side seams (12, 13).本発明は、パンツ型おむつ、生理用パンツ、失禁用パンツなどパンツ型吸収物品について言及する。パンツ型吸収物品は、前部分（２）と、後部分（３）と、股部分（４）と、を備え、前記前部分（２）および前記後部分（３）の横方向側部分（１７、１８、１９、２０）はそれらの内側表面が互いに面するように重ね合わせられ、前記パンツ型吸収物品の腰開口部（１４）および一対の脚開口部（１５、１６）を規定するように側部シーム（１２、１３）に沿って互いに接合される。前記横方向側部分（１７、１８、１９、２０）を含む前記前部分（２）および前記後部分（３）の少なくとも一部は、弾性積層体（２１）を備え、前記弾性積層体は第１の繊維層（２２）及び第２の繊維層（２３）とそれらの間に位置した弾性フィルム層（２４）とを備える。前記弾性積層体の着用者に面する内側を形成する前記弾性積層体（２１）の前記第１の繊維層（２２）は、１３ｇ／ｍ２～３０ｇ／ｍ２の坪量を有し、前記第１の繊維層（２２）の坪量は、前記弾性積層体の前記第２の繊維層（２３）の坪量より１０～３００％高くなっており、前記第１の繊維層（２２）は、前記側部シーム（１２、１３）に沿って互いに面する。
